yes, it does, with appropriate tuning/testing of the llm's parameters (temperature, top p, top k, using the right model, and the right prompt). You have to give it a rigid and very specific prompt to only answer in the JSON form. Also test it with LLMs that will handle being given a very low temperature to be very 'literal'. You're not asking for creative writing.

I should also add that the source comes from one of about 400 possible places and in a variety of messed up formats, it's the raw feed from a news scraper...
